MOWING OR REAPING MACHINE.

SPECIFICATION fonning part of Letters Patent No. 412,274, dated October8, 1889.

Application filed September 30, 1886. Serial No. 214,921. (No model.)

To ntZZ whom it 722 603, concern:

Be it known that I, EDWARD M. KRUM, a citizen of the United States,residing at Old Chathain, in the county of Columbia and State of NewYork, have invented certain new and useful Improvements in Mowing orReaping Machines, of which the following is a specification.

My invention relates to improvements in mowing or reaping machines; andit consists of the devices and parts and combinations of devices andparts, hereinafter particularly described, and specifically set forth inthe claims.

The objects of my invention are to provide in mowing or reaping machinescertain means by which the driver can easily and at will control theoperations of operating parts in the same, and also render certain partsmore effective than heretofore; and, further, to combine certainelements with certain operating parts of the machine, whereby moreadvantageous operations will be had than heretofore, all of which willbe hereinafter fully explained. I attain these obj ects by the meansillustrated in the accompanying drawings, in which there are twelvefigures, in all of which the same letters of reference refer to likeparts throughout the several views.

Figure 1 is a front view of a machine embodying the improvements in thisinvention. Fig. 2 is a rear side view of the same. Fig. 3 is a view fromabove of the same. Fig. 4: is a side elevation of the same with one ofthe driving-wheels removed. Fig. 5 is an enlarged view of the gearmechanism, drivewheel, axle-connections of the frames, and otherco-oper'ating parts. Fig. 6 is another view of the gear mechanism. Fig.7 is an enlarged view of the adjuncts of the cutter-bar shoe andcrank-shaft. Fig. 8 is a view of the crank-shaft connection with thecutter-bar from above. Fig. 9 is a sectional view of thepitman-wrist-pin box and sickle-bar pin. Fig. 10 is a side view of thewrist-pin box or hearing. Fig. 11 is a sectional view of the same, takenat line 1, Fig. 12. Fig. 12 is a sectional View taken at line 2 in Fig.10.

Referring to the drawings, A A are the driving-wheels, and B is the mainshaft or axle on which these wheels are loosely mount ed. This axle hasits hearings in sleeve 0, and tongue-frame D connects pole D with saidsleeve in the manner usually practiced by the trade. Wheels A Aare eachheld in connection with the axle or shaft B by a friction-clutch E.

A floating frame composed of portions F F F (shown by full and dottedlines in Figs. 1,

2, 3, and 4.) is arranged relatively below the axle-sleeve C and tongue-frame D. This floating tongue-frame is preferably made with itsport-ions F F F connected as one piece and arranged relatively in theform of a triangle below the axle of the machine, and it is jointed withthe axle or its sleeve by ears ff, Figs. 1, 3, 4., and 5, so as to becapable of vibrating vertically to elevate or depress its forward end,with which the cutting mechanism is connected. Portion F, of this frameruns diagonally from ear f to the front end of portion F, which holdsthe crankshaft C, and portion F is ext-ended roan wardly from theforward end of the crankshaft in a direction relatively parallel withthe sides of drive-wheels A, and is jointed with sleeve C by ear f, asshown in Figs. 1, 3, and a, and portion F is arranged relatively belowaxle-sleeve O and extends from ear f of portion. F to ear f of portion FA bracket F is extended rearwardly from portion F for supporting oneportion of the gear mechanism, Figs. 1, 2, 3, 4:, 5, and 6, forimparting motion to the crankshaft. The end portions 0 c of portion Fserve as bearings for crankshaft C. Bevel-gear G is connected with axleB so as to revolve with it.

Supported from bracket F extended from portion F of the floating frame,Figs. 5 and 6, is the internal gear G and'bevel-pinion G (preferablycast in a single piece,) mounted on a suitable spindleg, supported frombracket F and pinion g, working with the internal gear G, and suitablyconnected with sprocket-wheel H and mounted on a suitable spindle andalso supported from bracket F The revolution of bevel-gear G will ,through bevelgear G and pinion g, revolve sprocketwheel H.

Secured to the rear endof crank-shaft C is sprocket Wheel H, which isgeared with sprocket-wheel H by endless drive-chain H and secured to thefront end of the same shaft is the balance crank-wheel E, whichoperates, through a pitman, the sickle-bar.

I is the inner shoe connected with suspended arm I, which latter issuspended from portion F of the floating frame by ears 1' 2', Figs. 3,4, 7, and 8. The shoe I being thus suspended by means of its arms I fromthe portion F of the floating frame, it can be readily oscillated fromthe latter in either direction, so as to carry the shoe sidewise upwardfrom the ground and return.

Secured to shoe I is the finger-bar J, in which works the sickle-bar K.A wrist-pin j, secured with balance crank-wheel E, operates with apitman to impart to the sicklebar a reciprocating motion. When the shoeI,

by its arm I, is oscillated outwardly and upwardly, it wilLcarry with itthe entire cutting apparatus and elevate the outer end of the 1 shown inFigs. 1 and 4. The pressure of the same accordingly.

In the nose I of shoe I is secured the; This caster-wheel is connectedwith the nose of said shoeby the angular bracket M, thehorizoncaster-Wheel L, Figs. 1, 3, and 4.

tal limb m of which is pivoted to bracket m at the end of nose I whilethe vertical limb m is slotted and provided with an adjustable spindle mon which the caster-wheel revolves. By means of a screw-threaded nut onspindle m the latter can be adjusted at will to different heights abovethe surface of the ground, so as to carry the shoe at a .correspondingdistance above the same, and by the pivoting of the horizontal limb ofbracket M with the shoe the caster-wheel is rendered free to vibratehorizontally.

Secured to the rear side of shoe 1, and proj ecting outwardly from thesame, is the curved lifting-arm N, Figs. 1, 2, 3, 4, 7, and 8, havinggroove n for receiving lifting-chain n. Chain 71. connects wit-l1 thevolute-shaped lifting-cam Of This cam is connected with gear 0',(preferably a bevelgear,) and is mounted on a spindle held by a suitablebracket 0, projected upward from frame D, as shown in Fig. 4.

Pivoted to bracket 10, projected upward from tongue-frame D, issegment-gear P, working with gear 0, connected with volute cam 0. Madewith the segment gear-piece are ratchet teeth p, and lever-handle P,provided with pawl p operated by a lever-latch and connecting-rod in themanner usually practiced by the trade, enables the driver to operate atwill the segment-gear and through it and its coacting gear 0 revolve thevolute cam O to cause it to wind up chain n, and thereby cause the arm Iof shoeI (which carries the cutting apparatus) to swing upwardly andoutwardly by its ears z' z from portion F of the floating frame, whenthe cutting apparatus will be elevated from a horizontal position to avertical one, when the cutting apparatus can be readily moved to a shortdistance past a vertical position, so as to be slightly inclining, andthereby obviate the use of a locking device for holding the said cuttingapparatus up, and when the cutting apparatus is turned up from ahorizontal position the curved lifting-arm N will be in reversedposition on opposite side of portion F of the floating frame, with theend of liftingchain (connected with the shoe) relatively inward past theline of arm I, while the opposite end of said chain will have contactwith the external portion of the volute cam. A return of the cuttingapparatus to a horizontal position will be 'eifected by reversedoperations of the handled lever P.

Q is a duplex lever (shown in Figs. 1, 2, 3, and 4) arranged relativelyforward of the drivers seat, so that both its treadles q q can driversfoot on the forward treadle q will depress the forward end of thefloating frame, and consequently shoe I and the heel end of the cuttingapparatus carried by it. When the pressure is transferred to therearward treadle q, the forward end of the floating frame will beelevated, when the shoe and heel end of the cutting apparatus will becorrespondingly elevated. When the forward treadle q is operated at thetime lever-handle P is moved to a short distance, the heel end of thecutter-bar will be kept to the ground, while the outer end of the saidcutter-bar will be raised to pass any projecting substance; but

when rear treadle q is depressed and leverhandle 19 is idle, the heelend of the cutter-bar will be raised, so as to pass overany projectingsubstance at or near the heel of the cutterbar. Byoperating lever P to ashort distance at the same time the rear end of the duplex lever Q isdepressed the cutter-bar will be raised in its entire length to acorresponding position above the ground. It will therefore be readilyunderstood that by means of the lifting mechanism operated by lever Pand the duplex lever Q the driver has full control of the cuttingapparatus, and can, at will, elevate or depress the same, or raise ordepress its outer end only, or only elevate or depress its heel or shoeend of the same, as may be desired.

R is abifurcated draw-bar having its upper end supported in a suitableloose manner from pole D, while the ends of its limbs 1' 'r are jointedto the diagonal portion F of the fioatingframe, as shown in Figs. 1, 3,and 4. By this bifurcated draw-bar the draft of the animals is applieddirectly to the floating frame instead of to the main frame or pole, andthis floating frame will not be in the least affected by-the relativerise or fall of the pole when the machine is being drawn over unevensurfaces of the ground, while the shoe I of the cutting apparatus willbe maintained to the elevation set by the adjustment of the casterwheelwithout being materially raised or lowered by the draft of the animalsor the movements of the pole. 1

With the means of applying the draft of the animals to the machine thepole is employed simply to guide the machine for turning the same andfor properly supporting the devices which are attached to thetongueframe D.

Mounted on standard 8, projecting above the tongue-frame, is driversseat- S, which is pivoted to the horizontal end portion of standard s,so as to be capable of turning in direction of arrow 2. On the lowerside of seat S are gear-teeth t. (Shown in Fig. 2, and indicated bydotted lines in Fig. 3.) These gearteeth operate gear T, Figs. 1, 2, 3,and 4, mounted on shaft 11., which is supported by brackets a a,connected in a suitable manner with standards. Secured to the forwardend of shaft 16 is a crank-lever T, and jointed with the free end ofthis crank-lever is rod T which is jointed with the horizontal arm '2;of dog V, Figs. 5 and 6. This dog V is pivoted in a suitable manner withbracket F as shown illustrated in Figs. 5 and 6, and when arm n is in ahorizontal position, as shown by full lines in Fig. 6, this dog will beout of engageinent with the cogs of the internal gear G; but when saidarm is depressed the dog will engage with said gear and hold the samefrom revolving WV is a spring connecting with seat S and its standard. Sin direction of arrow 2 and hold it turned with its front side towardthe gear G, and when the seat turns in direction of arrow 2 the gearmade with the seat will operate gear T, actuating crank-lever U, andeffect a depression of the arm Q7 of dog V, andthrow the latter in withthe teeth of the internal gear G and hold it from revolving; but wh en.the seat is turned to position facing the front of the machine the gearst T will, through cranklever T and connecting-rod T operate to hold dogV out of engagement with the teeth of said gear, so that it can fullyrevolve. At a side of the seat is fixed a reacting lever '0, Figs. 3 andt, which projects forward so as to have bearing along the side of thedrivers leg, to aid him to hold the seat facing the front of themachine. lVhenever the seat is turned so as to face toward gear G, thedog V will be thrown into engagement with the internal gear and hold thesame from transferring motion from the bevel-gear G to the cuttingapparatus. It will be readily seen that should the driver from any causefall from the seat the spring XV will turn the seat on its pivot andthereby cause the gear mechanism T t and crank -lever T to throw dog Vinto engagement with the internal gear G, and thereby stop the movementof the cutting apparatus and prevent the driver from being injured byit. Another advantage is that when the driver is off the seat the seatwill be in position for holding the dog V in lookingengagement with gearG, when the driving This spring tends to turn seat wheels will be heldfrom revolving forward. In this case the mechanism operates as a braketo the wheels, and will check the animals from readily starting olf withthe machine in the absence of the driver.

I provide with bracket F Figs. 5 and 6, an adjustable sprocket-wheelbracket 72, which is pivoted on the stud or spindle g of the internalgear G. This bracket is provided with curved slot 72., which receivesthe spindle 721 of the sprocket-wheel H. This spindle 71- is made with ashoulder and a tightening-nut h by which it can be readily fixed afterthe said bracket 71-1138 been adjusted. By means of this adjustablesprocket-wheel bracket the slack of the sprocket-chain can at any timebe taken up.

X, Figs. 2 and 3,is a shifting cam mounted on sleeve 0 and working innotch w, made in portion F of the floating-tram e. This cam has a throwsufficient to move the floating frame to a distance sidewise from thebevelgear G equal to the depth of the cogs in the same, so as to movethe bevel-pinion G out of engagement with said gear, when thedriving-wheels of the machine will be free to revolve with out impartingmotion to other mechanism of the machine.

Y is the pitman for connecting the wristpin of the balance crank-wheel Ewith the reciprocating sickle-bar K. This pitman consists of the pivotedlever-jaws 3 y and tightening screw-bolt y, Figs. 7, S, and 9. The longends of these lever-jaws are made with recessed jaws ,2, preferablyconical-shaped, as shown in Fig. 9, and they hold the conical ends of apivot or pin, which passes through the car 70, Figs. '7 and 8, made withthe heel end of the sickle-bar. The opposite ends of these lever-jawsare made with conical cupshaped recesses e and receive the conicalshapedbox-bearin gs Z of the wrist-pin. These bearings are preferably made asillustrated in Figs. 10, 11, and 12, in which two opposite sides areslot/ted in direction of the axes of the bearings to within a shortdistance from being through the she1l,while with one of these slottedsides is slit 5 through to the bore of the bearing. Vlhenever either theconical ends of the pivot-pin or those of the bearing Z become worn thepitman can be readily tightened on the same by screwing the nut on thetightening-bolt 3 The track-clearers l are held in sockets i suitablyconnected, as praeticedby the trade, with a bracket i which isadjustably-pivoted to the heel of the outer shoe 1*, and is held withthe same by a screw-bolt, which can be loosened and tightened at will topermit the adjustment of the track-clearer to any desired position forclearing a good track.

Connected with the main frame or pole and attached to the same andarranged between the same and the floating frame is the elastic holderconsisting of a suitable spring S secured to the main frame or pole, anda suspension-chain S or jointed rod,) which con- IOC nects the saidspring with the floating frame. This device operates to give to theforward end of the floating frame" an elastic support, so as to causethe shoe I to bear more lightly on the ground than it would without thissupport.
